The following figure shows a direct connection, in which two devices are connected directly together.
As shown in the following table, Fab settings, topology settings, and available link speed depend on the settings of the packages and protocols used for the storage system connections, as well as whether the host mode option 51 is used. Host Mode Option 51 (Round Trip Set Up) improves host I/O response time for long distance (10 km) switch connections.
